Dengar's large blaster carbine was a modified MG-42 machine gun circa WWII. The folding
bipod stand was removed from underneath the main barrel. The hook that held the bipod in
the folded position was left in place and can be seen as a small protrusion in the picture
above. The wooden stock on the back was also removed.

Note: In many pre-production still photos Dengar is pictured holding a BlasTech DLT-19
(a modified MG 34). This was not the gun he had in the film, but it was used by 4-LOM.
